A lot of plumbings exist in factories and so on. It is difficult for humans to inspect them directly. Therefore, automated inspection by robots is desirable. However, many of existing inspection robots have to rotate the camera because a conventional camera can see only one direction while a piping has a cylindrical geometry. The use of an omni-directional camera is effective for the solution o...

This article describes an experimental investigation into the head tracking and control of a four-wheeled Omni-Robot. study described scheme omnidirectional mobile robot. Additionally, kinematics robot is presented., A with four Omni wheels was also developed on real hardware to verify controller architecture design. The system modeled then implemented Arduino Microcontroller. has two rotary en...

In this paper, we address the inverse problem of reconstructing a scene as well as the camera motion from the image sequence taken by an omni-directional camera. Our structure from motion results give sharp conditions under which the reconstruction is unique. For example, if there are three points in general position and three omni-directional cameras in general position, a unique reconstructio...

The number of robots applied to different jobs in our society has steadily increased over the past years. While industrial robots welding and varnishing our cars are quite common these days, the future generation of robots will enter our everyday life. In contrast to industrial robots working in special evacuated areas for security reasons, these mobile service robots will have to move among an...

In this paper, a new teleconference system by using Gigabit Ethernet based omni-directional camera system and flexible middleware system in realtime and bi-directional video transmission is introduced. The omni-directional image has more advantages than conventional one-directional camera in that it provides a wider view than a single directional camera and able to realize flexible teleconferen...

The use of wireless sensor networks to protect sensitive facilities or international borders has attracted more and more attention. In contrast to previous studies in which the barrier coverage problem was solved under the assumption of an omni-directional sensing model, the current study presents a scheme for constructing k-barrier coverage using randomly deployed sensors with directional sens...

ABSTRACT In this paper, we describe a design and construction method for an omni directional vision system and how to use it on autonomous robots for object detection, localization and also collision avoidance in middle size league of RoboCup. This vision system uses two mirrors, a flat and a hyperbolic one. The flat mirror is used for detecting very close objects around the robot body, moreove...

RoboCup (http://www.robocup.org) is an international worldwide initiative that aims to promote research and development in mobile robotics and related areas. Robotic soccer is one of the proposed problems since it represents a challenge of high complexity, in which fully autonomous robots cooperate in order to achieve a common goal (win the game). Within Robocup soccer competitions, the Middle-...

The development of microrobots on a millimeter scale has recently received much attention. The environments in which these robots are supposed to operate are narrow and potentially complicated spaces, such as micro-factory, blood vessel, and micro-satellite. The robots must have omni-directional mobility, high power and high load capacity, within a scale in millimeters, in order to accomplish t...

In this paper, we describe a new Telepresence system which enables a user to look around a virtualized real world easily in network environments. The proposed system includes omni-directional video viewers on web browsers and allows the user to look around the omni-directional video contents on the web browsers. The omni-directional video viewer is implemented as an Active-X program so that the...
